Subject [jira] Commented: (LUCENE-2649) FieldCache should include a BitSet for matching docs
Date Fri, 17 Sep 2010 14:10:36 GMT


Yonik Seeley commented on LUCENE-2649:

bq. Whatever you call it (using Factory is fine) but isn't that what you mentioned to be insufficient?
I mean this is something you would pass to a FieldCache.getXXX, right? 

I was suggesting handling it the same way as FieldCache.Parser - it's set on the SortField.
 But instead of just being able to control parsing of a term (which is too limited), it needs
to be able to control everything. (This would solve Shai's needs too)

> The FieldCache returns an array representing the values for each doc.  However there
is no way to know if the doc actually has a value.
> This should be changed to return an object representing the values *and* a BitSet for
all valid docs.
